Third, we present a single framework
that can be used to amplify both spatial motion and purely temporal
changes, e.g., the heart pulse, and can be adjusted to amplify particular
temporal frequencies—a feature which is not supported by
Lagrangian methods. Finally, we analytically and empirically compare
Eulerian and Lagrangian motion magnification approaches under
different noisy conditions. To demonstrate our approach, we
present several examples where our method makes subtle variations
in a scene visible.
